Abstract

The first part of this article attempted to refute the interpretation of Phd. 102a-107a as being the canonic place of the ontological argument in Platonic thought. The second part of this article will attempt to outline three objectives: to show that the ontological argument intervenes in Plato's thought not as a strict démonstration but as a central and permanent structure whereby the idea is necessarily deduced from the sensible; to show that this structure is also present in Saint Anselm's ontological argument as its philosophical meaning; to elucidate how Parmenides' ontology is the paradigm which inspired both Plato and Saint Anselm.
